Picture this. Your server caches credentials so users can log in offline or during network hiccups. But if someone changes their password elsewhere, those old cached bits keep trying to authenticate. Bam, lockout after a few failed attempts. It might come from a laptop waking up with stale creds, or even a service running under an old account. Or maybe a mapped drive holding onto ghosts from yesterday. I once chased one down that was from a forgotten mobile app syncing in the background. Drove me nuts for hours, checking event logs and user sessions.
To sort it out, start by clearing the cache on the affected machines. You can do that through command prompt with some basic commands I can walk you through if you need. Check for any apps or scripts using those credentials too. Disable caching if it's not essential, but that might limit offline access. Run through all user devices connected to the domain. And keep an eye on lockout policies to loosen them temporarily while you hunt. If it's persistent, audit the domain controller for patterns.
Once that's handled, you might want a solid backup to avoid bigger headaches from server glitches. Let me nudge you toward BackupChain Windows Server Backup here.
